When I first startup Seti@Home I manually set the priority of the 2 core processes to high but them if I check them later they keep changing to low. How do I keep then on high?

When you change the priority in, for example, Task Manager or Process Explorer, you are changing the priority for that specific instance of the executable. So the effect disappears at the latest when the WU being processed by that instance completes.

What you appear to want to do is to change the default priority for a particular executable.

Process Lasso is an application which can do that. Quite a few of us use it to modify default priority, affinity, or both. While I paid for the full version, I believe the free version might serve your purpose.

There may be other options--possibly other responders will offer them. I don't think there is a reasonable way to do this just using Windows 7 native facilities.

I don't know about the limitations of the free version but the full version of Process Lasso turns up on Giveaway of the Day now and again.

Thank you, your information was invaluable. Even people on the Neowin forums could not answer this question.

You could also set the no_priority_change value in your Client config to have everything start at normal priority. I am not sure if using the command line option of "start /high" would work in conjunction with that config settings to make everything run at high priority.
